The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure     the use of constant-time operations, which makes it easier for local users to discover a DSA private key     via a timing side-channel attack. (CVE-2016-2178)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of MySQL running on the remote host is 5.6.x prior to 5.6.34. It is, therefore, affected by multiple vulnerabilities :

  - Multiple integer overflow conditions exist in s3_srvr.c,     ssl_sess.c, and t1_lib.c due to improper use of pointer     arithmetic for heap-buffer boundary checks. An     unauthenticated, remote attacker can exploit this to     cause a denial of service. (CVE-2016-2177)

  - An information disclosure vulnerability exists in the     dsa_sign_setup() function in dsa_ossl.c due to a failure     to properly ensure the use of constant-time operations.
    An unauthenticated, remote attacker can exploit this,     via a timing side-channel attack, to disclose DSA key     information. (CVE-2016-2178)

  - A denial of service vulnerability exists in the DTLS     implementation due to a failure to properly restrict the     lifetime of queue entries associated with unused     out-of-order messages. An unauthenticated, remote     attacker can exploit this, by maintaining multiple     crafted DTLS sessions simultaneously, to exhaust memory.
    (CVE-2016-2179)

  - An out-of-bounds read error exists in the X.509 Public     Key Infrastructure Time-Stamp Protocol (TSP)     implementation. An unauthenticated, remote attacker can     exploit this, via a crafted time-stamp file that is     mishandled by the 'openssl ts' command, to cause     denial of service or to disclose sensitive information.
    (CVE-2016-2180)

  - A denial of service vulnerability exists in the     Anti-Replay feature in the DTLS implementation due to     improper handling of epoch sequence numbers in records.
    An unauthenticated, remote attacker can exploit this,     via spoofed DTLS records, to cause legitimate packets to     be dropped. (CVE-2016-2181)

  - An overflow condition exists in the BN_bn2dec() function     in bn_print.c due to improper validation of     user-supplied input when handling BIGNUM values. An     unauthenticated, remote attacker can exploit this to     crash the process. (CVE-2016-2182)

  - A vulnerability exists, known as SWEET32, in the 3DES     and Blowfish algorithms due to the use of weak 64-bit     block ciphers by default. A man-in-the-middle attacker     who has sufficient resources can exploit this     vulnerability, via a 'birthday' attack, to detect a     collision that leaks the XOR between the fixed secret     and a known plaintext, allowing the disclosure of the     secret text, such as secure HTTPS cookies, and possibly     resulting in the hijacking of an authenticated session.
    (CVE-2016-2183)

  - An unspecified flaw exists in the Optimizer subcomponent     that allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-3492)

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-5584)

  - An unspecified flaw exists in the MyISAM subcomponent     that allows a local attacker to gain elevated     privileges. (CVE-2016-5616)

  - An unspecified flaw exists in the Error Handling     subcomponent that allows a local attacker to gain     elevated privileges. (CVE-2016-5617)

  - An unspecified flaw exists in the GIS subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-5626)

  - An unspecified flaw exists in the Federated subcomponent     that allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-5629)

  - A flaw exists in the tls_decrypt_ticket() function in     t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A flaw exists in the ssl_parse_clienthello_tlsext()     function in t1_lib.c due to improper handling of overly     large OCSP Status Request extensions from clients. An     unauthenticated, remote attacker can exploit this, via     large OCSP Status Request extensions, to exhaust memory     resources, resulting in a denial of service condition.
    (CVE-2016-6304)

  - An out-of-bounds read error exists in the certificate     parser that allows an unauthenticated, remote attacker     to cause a denial of service via crafted certificate     operations. (CVE-2016-6306)

  - A flaw exists in the check_log_path() function within     file sql/sys_vars.cc due to inadequate restrictions on     the ability to write to the my.cnf configuration file     and allowing the loading of configuration files from     path locations not used by current versions. An     authenticated, remote attacker can exploit this issue     by using specially crafted queries that utilize logging     functionality to create new files or append custom     content to existing files. This allows the attacker to     gain root privileges by inserting a custom .cnf file     with a 'malloc_lib=' directive pointing to specially     crafted mysql_hookandroot_lib.so file and thereby cause     MySQL to load a malicious library the next time it is     started. (CVE-2016-6662)

  - A flaw exists in wolfSSL, specifically within the C     software version of AES Encryption and Decryption, due     to table lookups not properly considering cache-bank     access times. A local attacker can exploit this, via a     specially crafted application, to disclose AES keys.
    (CVE-2016-7440)

  - An unspecified flaw exists in the Types subcomponent     that allows an authenticated, remote attacker to cause     a denial of service condition.(CVE-2016-8283)

According to its self-reported version, the MySQL Enterprise Monitor application running on the remote host is 3.1.x prior to 3.1.5.7958.
It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the     bundled version of Apache Tomcat in the Manager and Host     Manager web applications due to a flaw in the index page     when issuing redirects in response to unauthenticated     requests for the root directory of the application. An     authenticated, remote attacker can exploit this to gain     access to the XSRF token information stored in the index     page. (CVE-2015-5351)

(CVE-2016-2183)

  - A flaw exists in the bundled version of OpenSSL in the     tls_decrypt_ticket() function in t1_lib.c due to     improper handling of ticket HMAC digests. An     unauthenticated, remote attacker can exploit this, via a     ticket that is too short, to crash the process,     resulting in a denial of service. (CVE-2016-6302)

An     unauthenticated, remote attacker can exploit this, via     large OCSP Status Request extensions, to exhaust memory     resources. (CVE-2016-6304)

  - An out-of-bounds read error exists in the bundled     version of OpenSSL in the certificate parser that allows     an unauthenticated, remote attacker to cause a denial of     service via crafted certificate operations.
